LAM P PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 741,129, dated October13, 1903. Application filed February 6. 1908. Serial No. 142,168. (Nomodel.)

To all whom it may concern:

Be it known that 1, WILLIAM H. GREEN- WOOD, a citizen of the UnitedStates, residing at Everett, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inLamp-Protectors; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to protectors or guards for the bulbs ofincandescent electric lamps;and it consists in the novel constructionand combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a vertical sec' tion through the protector,showing it closed.

Fig. 2 is a side view showing the protector open. Fig. 3 is a plan Viewof the hinged ring at the bottom of the protector.

A is a clamping device at the top of the protector, preferablyconsisting of two semicircular bands having flanges a, which areconnected by screws or bolts 1) or in any other approved manner, so thatthe protector is thereby secured to the socket of the lamp, which isshown in dotted lines in Fig. 1.

B B are two shields formed of Wires. The upper ends of the wires areconnected to the clamping-bands, and their lower ends are connected tothe hinged halves of a ring 0. The ring 0 may be circular, oval, or ofother approved shape, and-its halves are pivoted together in anyapproved manner. The two shields together form a wire cage, which has anoutline similar to the shape of the lampbulb and which incloses it. Theshields are provided with one or more cross-wires c for holding the mainwires at the preferred distauces apart from each other.

D represents inner guard-wires arranged longitudinally inside the cageand provided with coiled springs d where they bear against the peripheryof the glass bulb of the lamp. These springs yield and accommodate.themselves to the variations of the bulbs in size and prevent the bulbsfrom coming in contact with the wires of the cage.

Four inner yielding guards D are prefer ably used, two for each shield;but any other number may be applied as found desirable.

WVhat I claim is 1. A lamp-protector, comprising a wirework cage formedof two parts hinged together and provided with fastening devices, and aseries of yielding guards arranged longitudinally inside the said cageand engaging the bulb of the lamp, substantially as set forth.

2. A lamp-protector,comprising two shields formed of longitudinal wiresand cross-wires, said shields being hinged together and provided withfastening devices, and a series of inner guard-wires provided withyielding coiled springs and extending longitudinally between thesaidcross-wires and the lower parts of the said shields, substantiallyas set forth.

In testimony whereof I affix my signature in presence of two witnesses.
